Growth of HgBa2CaCu2Oy films with a buffer layer

Using YBa2 Cu3 O7 (YBCO) as a buffer layer high Tc superconducting HgBa2 CaCu2 Oy (Hg-1212) thin films with zero resistance temperature (Tc ) of 115-124 K and critical current density (Jc ) of 1 MA cm-2 at 77 K in zero magnetic field have been grown on (100)Y-ZrO2 substrates. The high Tc , Jc and good morphology indicate that YBCO is a good buffer for growing the Hg cuprate films. This novel buffer makes it possible to grow Hg cuprate films on many substrates, including some metallic tapes.
